[patch] fix impliedness of -Wunused-parameter depending on -Wexta option ordering


This fixes a regression introduced with 4.8, where the option ordering of
-Wextra and -Wunused-parameter emits a warning, which is not emitted with 4.7.
No regressions with the trunk, the 4.9 and 4.8 branches. Ok to check in for these?
